HP 3PAR AIX and IBM Virtual I/O Server Implementation Guide

Specific cabling setup and connectivity guidelines need to be followed for HP 3PAR OS Persistent
Ports to function properly:
• HP 3PAR StoreServ Storage FC partner ports must be connected to the same FC Fabric and
switch.
• The FC fabric being used must support NPIV, and NPIV must be enabled.
• The host–facing HBAs must be configured for point-to-point fabric connection (there is no
support for direct-connect “loops”).
HP 3PAR OS Persistent Ports Limitations
When the FC target port fails over to its partner port as part of the HP 3PAR OS Persistent Ports
feature, I/O will be redirected by the HP 3PAR StoreServ Storage to the partner port. During the
persistent port failover, an AIX host may detect and report a temporary path loss in the AIX errpt
log. This applies to HP 3PAR ODM installations as well as to Symantec Storage Foundation/DMP
installations with AIX and HP 3PAR StoreServ Storage.
The HP Persistent Ports feature is not supported with iSCSI.
